Consider the net of a triangular prism where each unit on the coordinate plane represents four feet. if a sheet of plywood measures 4 ft x 8 ft, how many sheets of plywood will a carpenter need to build the prism?
a) 3
b) 3.5
c) 4
d) 4.5

The answer would be C. Multiply 4 and 8 which is 32 then divide that by 8 which equals 4.

check the picture below.

well, the angle at the vertex d is clearly not a right-angle, let's check for the one at the vertex f which does look like,   however if it's indeed, that means ef is perpendicular to df, in which case their slopes will be negative reciprocal of each other.

so the negative reciprocal of the slope of ef is 1, however the slope of df is not 1, is 1/2, so nope, they're not perpendicular lines.

the answer is a i belaeve atleast thats what my calculator just gfave me
